TJ Murphy is a veteran marathon runner, triathlete, former editorial director of a number of fitness magazines and a NYT best selling author.

He tried CrossFit Endurance “with the attitude that I would do it 100% so that I could test it in a valid way and prove that it was wrong for me. A month later and I was ticked off at myself for not having found it sooner,” Murphy said.

Since setting his preconceptions aside, and finding success and fun with CFE, Murphy has co-written a book with CFE founder Brian MacKenzie to set the record straight on: the difference between CrossFit and CrossFit Endurance; what CrossFit Endurance really is (not what the critics think it is); and how athletes, regardless of their backgrounds, can use the CFE program to tackle any distance from a 5K to an ultramarathon.
